Laurie bought 4 yards of brown braid trim, 7 yards of black lace, and 13 yards of gold ribbon. She paid $2.40 for each yard of ribbon. How many total yards did she buy of trim, lace and ribbons? How much did Laurie spend on her purchases before tax? This is probably easy, but i am too lazy. Also if you want, type the steps that got you your answer. I will give you brainliest for my laziness.

24 yards, $77.40

Step-by-step explanation:

1) brown braid : 4*2.40 = $16.80

black lace : 7*2.40 = $29.40

gold ribbon : 13*2.40 = $31.20

2) 4 + 7 + 13 = 24 yards <

3) 16.80 + 29.40 + 31.20 = $77.40 <

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
